Looking to buy a van and I want to keep it Vw . Not many options so its going to be a Mk3 Caddy. From what I have read so far its based loosely on the mk5 chasis. Wondered if it has 50 or 55mm suspension ? And can the seats be swapped out for gti ones, braking - gti stoppers up front. Gti pedals inside , some bbs ch for rims , front bumper upgrade to touran or carrera cup stuff.
